Hi Guys,
I will like to know how your 3.73 performs with the 275/40R19 upgrade compared to stock setup?. I'm planning to go that way but will like some feedback.

I cant speak for anyone else but the 19" tires can get expensive, my last set was 1550$ installed, although that was a w or a v rated tire 186 mph...the ride is noticably stiffer but the brakes are an eye opener, pulled down to 40 mph from about 150 and it is violent stopping power. With the 19's get the brembos...will almost instantly goto full lock up abs firing like crazy from 100 mph with little to no effort. I see no point in having a fast car without fast brakes. I am looking at dropping to 3.55 rear end gears as 70 mph in 6th is 2200 rpm or so...although it will easily exceed the 160 mph speedometer...

I am also taking several assumptions...18 tires regular brakes, no front strut tower...
